In the process of sheet metal processing, the service life of the tool directly affects production efficiency, processing quality, and manufacturing cost. Due to the wide variety of sheet metal materials (such as cold-rolled steel plate, stainless steel plate, galvanized plate, etc.), and the frequent occurrence of high-speed cutting and large friction during processing, tools are prone to wear and even damage. Therefore, how to effectively extend tool life has become an issue that sheet metal processing enterprises must pay attention to. This article will discuss effective strategies for extending tool life from multiple aspects.

　　One, reasonable selection of tool material and type



Different sheet metal materials have different requirements for tools. For example, when processing stainless steel, it is necessary to choose hard alloy or coated tools with high hardness and good thermal resistance; while for ordinary carbon steel, tool steel tools with relatively lower prices can be selected. In addition, it is also crucial to choose the appropriate tool type according to the processing method (stamping, shearing, bending, punching, etc.). Suitable tools can not only improve processing efficiency but also effectively reduce wear and extend service life.

　　Two, optimize cutting parameter settings



Cutting speed, feed rate, and cutting depth are key parameters affecting tool life. Excessive cutting speed will intensify tool heating and accelerate wear; an excessive feed rate will increase cutting force, leading to tool chipping. Therefore, in actual operation, cutting parameters should be reasonably set based on material properties, equipment performance, and tool type, achieving 'high speed in moderation, feed rate uniformity' to reduce tool wear.

　　Three, strengthen cooling and lubrication measures



In the process of sheet metal processing, the rational use of coolant can effectively reduce cutting temperature, reduce friction between metal and tool, and thus extend tool life. Especially in high-speed stamping or continuous processing, cooling and lubrication are particularly important. At the same time, the cooling system should be checked regularly to ensure the smooth circulation of coolant, avoiding abnormal tool wear caused by insufficient cooling.

　　Four, standardized operation and regular maintenance



Improper human operation is also an important reason for abnormal tool wear. Therefore, operators should receive professional training, be familiar with equipment performance and operation procedures, and avoid rough handling that leads to tool damage. In addition, tools should be regularly inspected and maintained during use, and worn-out tools should be replaced in time to avoid affecting the overall service life due to local wear intensification.



Five, maintain the good condition of processing equipment



The precision and stability of machine tools directly affect the working state of the tool. If there are problems such as equipment vibration and excessive spindle clearance, it will lead to uneven force on the tool and accelerate wear. Therefore, enterprises should regularly inspect and maintain equipment to ensure its good operating condition and provide a stable processing environment for the tool.



In summary, extending the tool life in sheet metal processing is a systematic project, which requires multiple aspects to be addressed, such as tool selection, parameter setting, cooling and lubrication, operation specifications, and equipment maintenance. Only by comprehensively considering and implementing various measures in actual production can tool wear be effectively reduced, processing efficiency be improved, and higher economic benefits be brought to the enterprise.
